Leyton Orient have parted company with manager Geraint Williams in the wake of Saturday's 3-1 home defeat by fellow strugglers Hartlepool.
The Os have won just one of their last 11 games and are now hovering just a point above the League One relegation zone. Assistant manager Kevin Nugent will take charge on a caretaker basis for Monday's clash at Southampton.
Chairman Barry Hearn told the club's official website: "The performance against Hartlepool was abysmal and ultimately the responsibility for that lies with the manager."
He added: "We're on a dreadful run of form and this decision has been taken in order to give us the best chance of staying in League One.
"Geraint is as honest and professional a manager as you will find in football and it's unfortunate things have not worked out, but I thank him for his efforts and I wish him every success in the future."
